Limitations
The following conditions must not be coated with Polycoat
Products deck coating systems or products: on grade slabs,
split slabs with buried membrane, sandwich slabs with
insulation, slabs over unvented metal pan, magnesite, or
concrete with a structural integrity less than 3000 psi. Asphalt
surfaces and asphalt overlays may be coated with Polycoat
decking systems if first coated with the Polycoat™ PC-IM 129.
Concrete must exhibit 3000 psi minimum strength. Concrete
surfaces to be coated must be trowel finished in compliance with
the American Concrete Institute (except that hand troweling
is not required), followed by a fine-haired brooming, left free
of loose particles, and shall be without ridges, projections,
voids and concrete droppings that would be mechanically
detrimental to coating application or function. New concrete
must be cured for 28 days.

Polycoat Products coating systems should not be subjected
to rising water tables or hydrostatic pressure on slab-on-
grade decks. The only acceptable grade of plywood is APA
rated exterior grade or better. The appearance and physical
characteristics of the plywood and grade should be considered.
Plywood should be new or cleaned and sanded (see General
Guidelines). Coating should be applied at least 5°F (3°C) above
the dew point.
